The Wall – Live in Berlin was a live concert performance by Roger Waters and numerous guest artists, of the Pink Floyd studio album The Wall, itself largely written by Waters during his time with the band. The show was held in Berlin on 21 July 1990, to commemorate the fall of the Berlin Wall eight months earlier. A live album of the concert was released 21 August 1990. A video of the concert was also commercially released.

The show had a sell-out crowd of over 350,000 people, and right before the performance started the gates were opened which enabled at least another 100,000 people to watch.[4] While this broke records for a paid-entry concert, 7 days earlier Jean Michel Jarre had set a new world record for concert attendance, with his free Paris la Defense show attracting a live audience of two million.

The event was produced and cast by British impresario and producer Tony Hollingsworth. It was staged partly at Waters' expense. While he subsequently earned the money back from the sale of the CD and video releases of the album, the original plan was to donate all profits past his initial investment to the Memorial Fund for Disaster Relief, a UK charity founded by Leonard Cheshire. However, audio and video sales came in significantly under projections, and the trading arm of the charity (Operation Dinghy) incurred heavy losses. A few years later, the charity was wound up, and the audio and video sales rights from the concert performance returned to Waters.

The production was designed by Mark Fisher and Jonathan Park.[5][6][7] The stage design featured a 550-foot-long (170 m) and 82-foot-high (25 m) wall. Most of the wall was built before the show and the rest was built progressively through the first part of the show. The wall was then knocked down at the end of the show.[8]

Waters had stated on the first airing of the making of The Wall on In the Studio with Redbeard in July 1989 that the only way he was to resurrect a live performance of The Wall was "if the Berlin Wall came down". Four months later the wall came down.

Initially, Waters tried to get guest musicians like Peter Gabriel, Bruce Springsteen and Eric Clapton but they were either unavailable or turned it down. Both Rod Stewart, who was to sing "Young Lust", and Joe Cocker were originally confirmed to appear but when the original planned concert date was put back both found themselves unavailable.[9] Also, on the same 1989 interview with Redbeard, Waters stated that "I might even let Dave play guitar." On 30 June 1990 backstage at the Knebworth Pink Floyd performance at Knebworth '90, during a pre-show interview, David Gilmour responded to Roger's statement on an interview with Jim Ladd by saying that "he and the rest of Pink Floyd (Nick Mason and Rick Wright) had been given the legal go-ahead to perform with Roger but had not been contacted." Two days later, on 2 July 1990 Waters appeared on the American rock radio call-in show Rockline and contradicted his Gilmour invite by saying, "I don't know where Dave got that idea".

This performance had several differences from Pink Floyd's original production of The Wall show. Both "Mother" and "Another Brick in the Wall, Part II" (like in the 1980/81 concerts) were extended with solos by various instruments and the latter had a cold ending. "In The Flesh" (also like the 1980/81 concerts) has an extended intro, and "Comfortably Numb" featured dueling solos by the two guitarists as well as an additional chorus at the end of the song. "The Show Must Go On" is omitted completely, while both "The Last Few Bricks" and "What Shall We Do Now?" are included ("The Last Few Bricks" was shortened). Also, the performance of the song "The Trial" had live actors playing the parts, with Thomas Dolby playing the part of the teacher hanging from the wall, Tim Curry as the prosecutor, and Albert Finney as the Judge. The show officially ended with "The Tide Is Turning", a song from Waters' then-recent solo album Radio K.A.O.S. The Wall's classic closing number, "Outside the Wall," was affixed to the end of "The Tide is Turning."

The Wall – Live in Berlin was released as a live recording of the concert, although a couple of tracks were excised from the CD version, and the Laserdisc video in NTSC can still be found through second sourcing. A DVD was released in 2003 in the USA by Island/Mercury Records and internationally by Universal Music (Region-free).

Hollingsworth's company Tribute, a London-based "good causes" campaign company, sold worldwide television rights, with 52 countries showing the two-hour event. Twenty countries showed up to five repeats of the show and 65 countries broadcast a highlights show. There was also distribution of a double music CD and post-production VHS videotape by Polygram.

The live performance of "Mother" was also hounded by a power failure. Roger Waters tried to get Sinéad O'Connor to sing her parts anyway, or mime the song, while the error was being fixed. Offended by being asked to mime, she didn't return after the show to re-record the performance (which is how "The Thin Ice" was saved for the CD/Video release.) Instead, the release version of "Mother" comes from the dress rehearsal on the previous night before the concert. Consequently, the large projection of Gerald Scarfe's mother character that was projected on the screen during the concert cannot be seen on the video or DVD versions.

Film director Ian Emes was hired to shoot live footage originally intended to be included in the program. Emes created a film about the character of Pink, performed by Rupert Everett, and of Pink's mother, played by Marianne Faithfull, and shot the sequences in East Berlin during the concert preparations. Only a small segment of the film was used in the performance.

The Wife's part of "The Trial" was reshot at London's Brixton Academy after the original sequence was deemed to be of insufficient quality due to camera shake. What is seen in the video issue is a close-up of Ute Lemper, shot against a dark background, lip-syncing to the original live sound.[9]

Shot on Potsdamer Platz, the no man's land between East and West Berlin, the producers didn't know if the area would be filled with mines. Before setting up, they did a sweep of the area and found a cache of munitions and a previously unknown SSLeibstandarte Adolf Hitler bunker.[10]

At the request of the concert producers, part of the Berlin Wall was kept in place as a security fence behind the stage.

During the final chanting of "Tear down the wall!" in the Trial sequence, the wall has a projection of a concrete and graffiti marked semblance of the Berlin Wall, just before it is torn down.

^According to Roger Waters' recollections in the documentary supplied with the DVD release of the film: "They stopped charging people when we got to 350–360,000, and like another 100,000 people came in..."
